IMPROVEMENT IN VEHICLE-SPRINGS.

Specification forming part of Letters Patent No. 204,915, dated J nne18, 1878 application filed May 3, 1878.

To all whom it may concern:

Be it known that I, SAMUEL M. RlCHARD- soN, of Boston, county ofSuffolk, State of Massachusetts, have invented an Improvement in Wagons,of which the following is a specification:

This invention relates to wagons, and has special reference to devicesfor supporting the box, such devices being intended as substitutes forthe ordinary wooden side rods of the socalled road-wagons, to avoid thejar common to such wagons, and make them ride more easily.

Figure 1 represents, in side elevation, a wagon constructed inaccordance with my invention, the wheels being omitted;-Fig. 2,,a bottomview thereof; Fig. 3, a section on the line as m, Fig. 2; and Fig. 4, anend view.

The box a is shown as a square box. 1) represents the rear axle c, thefront axle; d, the cross-bar thereon; and e, the reaches or rodsconnecting the two axles, all as usual. The box is supported at eachcorner by means of curved springsf, (shown connected with straps g,secured to the box, and with the axle b or cross-bar d,) the ends f offprojecting toward the center of the wagon to stiffen the springs h,which are also attached to the axle b and cross-bar. These springs hproject back of the rear axle, as at h, and in front of the crossbar, asat 71/2, to stiffen the springs f, and at their other ends they areconnected with ears i at the ends of the elliptic half-springs It,attached to cross-pieces lat the bottom of the box, such springs ishaving one or more leaves, as may be desired.

It is obvious that the stiffness of springs f h may be regulated byextending their ends one over the other, more or less.

If desired, a third spring may be attached and extended under springs fand h, to produce a very stiff spring, and the reaches 0 may be entirelyomitted.

This construction of road-wagons obviates the jar common to the use ofwooden springs, and makes a very strong, light, and easy riding wagon.

By employing the springs k, to which to connect springs h, rather thanconnecting such springs h directly to the sides of the box, 1 am enabledto balance the box, so that it will remain more nearly in a horizontalposition .under the action of weight in the box.

I claim- 1. The springs f, attached at one end to the box, and havingtheir other ends projecting inwardly beyond the point of attachment tothe axle or cross-bar, in combination with springs h, extendinginwardly, and attached to cross-springs k, and projecting outwardly,-

so as to overlap and stiffen the springs f, substantially as described.

2. The combination of springs f f and h h h with the cross-springs 7cand the box, axle, and cross-bar of a wagon, when constructed andarranged substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
